Abstract
The invention provides a coaxiality detector. The coaxiality detector is used for detecting the coaxiality of a hexagonal shaft, and comprises a base, a clamping mechanism, a slewing mechanism and a detection device, wherein the clamping mechanism is used for clamping the hexagonal shaft; the slewing mechanism is movably arranged on the base, and is used for supporting and driving the clamping mechanism to rotate around the central axis of the hexagonal shaft; and the detection device is arranged on the base and is used for detecting the coaxiality of the hexagonal shaft. The coaxiality detector provided by the invention adopts a precision three-jaw chuck and is connected with the base through a bearing, so that the precision three-jaw chuck cannot jump when the precision three-jaw chuck rotates in the center of the base freely; and simultaneously, the hexagonal shaft is clamped on and detached from the three-jaw chuck very conveniently; the installation error is low; and the detection precision is improved.
Description
Technical field
The present invention relates to a kind of coaxiality detector, particularly a kind of coaxiality detector for detection of hexagonal axis.
Background technology
Hexagonal axis is the vitals on the automobile, is welded by piston pin and hexagon, and it has very high requirement to right alignment.The right alignment of traditional measurement hexagonal axis is that its hexagonal end is clipped in the scroll chuck of lathe, is measuring beating of piston pin on the hexagonal axis with dial gauge again, and the method operation requirements is high, and can produce larger error, wastes time and energy.
Summary of the invention
The technical matters that (one) will solve
The technical problem to be solved in the present invention provides the coaxiality detector that a kind of clamping is quick, alignment error is little, accuracy of detection is high.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of coaxiality detector, for detection of the right alignment of hexagonal axis 4, comprise base 3; Clamping mechanism, it is used for the described hexagonal axis 4 of clamping;
Slew gear is installed on the described base 3, is used for supporting and driving described clamping mechanism and rotates around the central shaft of described hexagonal axis 4; Pick-up unit, it is installed on the described base 3, for detection of the right alignment of cylindrical and the hexagon of described hexagonal axis 4.
